VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 408,519, dated August 6, 1889.

V Application filed May 7, 1889. Serial 110,309,963. (N0 model.)

To all whom it may-concern..-

Be it known that I, WILLIAM E. POWERS, a citizen of the United States, residing at Hastings, in the county of Barry and State of Michigan, have invented certain new and useful Improvements in Vehicle-Springs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to springs that are particularly designed for'vehicles, and aims to provide'a spring that will support a given load under a given tension, and which will be self-re-enfo'rcing in the event of the given load being exceeded or an abnormal strain coming on the spring.

The improvement consists of the novel features, which will be hereinafter more fully described and claimed, and which are shown in the annexed drawings, in which Figure 1 is a side View of a vehic1e-body, showing the application of my invention. Fig. 2 is a bottom plan view of my spring.

. Fig. 3 is a perspective view showing the op eration of the sprii'ig by dotted lines.

The spring is composed of two members 0 and D,'whi ch have their inner ends bent in opposite directions to form the armsA and E, and which have their outer ends bent in the same direction to form the arms 0 and (1, respectively. The arms 0 and d are connected at their outer ends in any desired manner, and are bent to form the hook B, which is connected by shackle E with the axle F or other support. Thearm E normally stands at an angle to the bottom G of the'vehicle or other support to which the spring is secured. When the spring-arms c and d move a certain distance, the arm E is brought in contact with the support G and increases the resistance to the further movement of the said spring-arms c and dz'. e., it re-enforces said arms and increases their capabilities of sustainin g a greater load.

It will be observed that the member D is held to the support G by staples, and that said member is adapted to turn sufficiently to permit the arm E to come in contact with the said support G. The member D,with the arms d and E, may be separate from the member O, and its arms 0 and A being provided to supplement or re-enforce the latter; but for economy of construction it has been found expedient to construct them of a single rod, which is bent substantially in the form shown.

Having thus described my invention, what I claim, and desire to secure by Letters Pattent, is-

1.'The combination,with the spring composed of the member 0 and the arm 0, of the re-enforcing spring composed of the member D, the arm d, connected at its outer end with arm a and the arm E, the latter adapted to normally stand at an angle to the support to which the spring is secured, substantially as and for the purpose described.

2. The combination, with the member 0, having the spring-arm c, of the member D, having the arm (I, which is connected with the arm 0, and having the arm E, which stands at an angle to the support to which the spring is secured, substantially as set forth.

3. The herein-described spring, composed of the parallel members 0 and D, the arms 0 and (l at the outer ends of the members 0 and D, respectively, extending in the same direction and connected together, and the arms A and E at the inner ends of said members, the arm E extending in an opposite direction to the arm A and projecting up at an angle, substantially as described, for the purpose specified.

In testimony whereof I affiX my signature in presence of two witnesses;

WVILLIAM E. POWERS.
